Manta Network to Enable On-chain Private Identity in Arbitrum Ecosystem

4 min readMay 9


Manta Network is proud to support Arbitrum to roll out a series of Private Soul Bound Tokens (zkSBTs) to provide private on-chain identity verification for Arbitrum users and its ecosystem. This offers users a decentralized, trustless, and private way to verify their real identities without compromising any information or data leakage about their on-chain activity. Through the new zkSBT offerings launching starting today on Manta Network’s NPO, Arbitrum users will be able to privately verify various aspects of their on-chain identity without revealing any additional information. Throughout the week, users will have access to various zkSBTs designed for verification of Arbitrum ecosystem supporters and users:

  1. Today, on May 9, 2023, Arbitrum users will be able to mint the ARB Early Supporter zkPass, which is a private verifiable proof of participation as an early supporter within the Arbitrum ecosystem (prior to token launch). Anyone who received tokens in the Arbitrum airdrop qualifies to mint an ARB Early Supporter zkPass.
  2. On Thursday, May 11, 2023, Arbitrum users will be able to mint a zkSBT from one of Manta Network’s ecosystem projects, ReadOn.
  3. Furthermore, with this enablement of Arbitrum identity, future zkSBTs for the Arbitrum ecosystem can be released as well in conjunction with other Manta ecosystem activities and projects with Arbitrum.

All three zkSBT mints will be available indefinitely; i.e., users can mint their zkSBT at any time by verifying their credentials through an Arbitrum-supported wallet and minting/storing the zkSBT on the Manta Wallet. More details about each of the zkSBTs will be available shortly.

The Existing On-Chain Identity Problem

With the current state of public blockchains, every on-chain action is recorded, immutable, and fully transparent. While this transparency was originally necessary to provide trustless verifiability, it created many issues around surveillance, non-consenting data access, and, ultimately, an infringement on user safety and security when performing actions on-chain. Fortunately, Manta Network’s implementation of zero-knowledge proofs enables the same on-chain trustless verifiability without the necessity of full on-chain transparency. As a result, users are able to benefit from a seamless, modular privacy experience.

Manta Network’s research into zero-knowledge proof circuits has been implemented into one of its flagship platforms, the NPO, allowing users to mint zkSBTs. zkSBTs are on-chain, verifiable credentials that offer a trustless layer of privacy. Combined with proof keys, users can verify their ownership of zkSBTs without even connecting a wallet, enabling a seamless and modular privacy experience when interacting with applications.

Minting your Arbitrum zkSBTs

To mint your Arbitrum zkSBTs, you’ll need:

  1. An Arbitrum-compatible wallet that you hold your Arbitrum assets in, such as MetaMask;
  2. The correct credentials to verify your eligibility for minting a corresponding zkSBT;
  3. The Manta Wallet to hold your minted zkSBT.

You can head over to the Manta Network NPO platform to mint your Arbitrum zkSBTs. For a full tutorial on how to mint zkSBTs, please check out our guide here.
